stages of kaolin production

Phase transformations in clays and kaolins produced by thermal .The results indicate that in samples of kaolin and ball clays the α -alumina phase (corundum) appears in the first chlorination stage. This phase disappears at longer chlorination times due to the volatilization of AlCl3.
